# FetchXML

**FetchXML** defines your request to the database (your "query for data", not unlike a SQL query) by specifying which Entity Set you would like to query (eg opportunity, account, contact etc), and the **fields** you would like to be made available on each entity that the query returns in its results. It controls how the data is filtered, and how you want that data to be sorted.\
\
This is a very neat way of providing data from within Dynamics for use within Keyfax scripting.  \
\
There is a wealth of documentation and FetchXML examples on the internet; for more information [click here](https://docs.microsoft.com/en-us/powerapps/developer/common-data-service/use-fetchxml-construct-query).

{% hint style="info" %}
**TIP** The [XrmToolbox](https://www.xrmtoolbox.com/) contains useful FetchXml tools to assist in query development (particularly syntax checking).
{% endhint %}

The **Active FetchXML view** provides a a summary of all available FetchXML queries#, e.g:

<figure><img src="/files/WxgkZMOKHOm8oWlFYWu8" alt=""><figcaption></figcaption></figure>

Although several example **FetchXML** look ups are shipped with KeyNamics and may provide some guidance, crafting more complex **FetchXML** statements may prove a little more tricky so if any further assistance is required, please [Contact Us](/links/support.md).
